The City of Gold campaign exists of four (4) heists:

• Dragon Heist
  
• The Ukranian Prisoner
  
• Black Cat
  
• Mountain Master

1. Each of these heists contains one baggable Tea Set loot item that must be secured in each heist.
   
2. All tea sets can be obtained either in stealth or loud on any difficulty.
   
3. Complete/finish each heist after securing each set.
   
4. You must replay Dragon Heist if you haven't after the Mountain Master update; if you have secured the tea set before this update it does not count.

if I see one of my guides being published on your stinky "gameplay tips" website again im gonna send the PAYDAY-gang after you.
